Optic nerve thickening and infarction as the first evidence of orbital involvement with mucormycosis

We report a 53-year-old female with uncontrolled diabetes mellitus who presented with decreased vision in the right eye for a few hours duration. Orbital computed tomography and magnetic resonance imaging were performed at presentation and showed a thickening and infarction of the right optic nerve with no other orbital abnormalities. A few days later, the patient developed necrosis in the region of the right medial canthus and nasal mucosa. Tissue biopsy confirmed the diagnosis of mucormycosis

Slow-growing large pleomorphic adenoma of ectopic lacrimal gland tissue in the upper eyelid

A few cases of pleomorphic adenoma of an ectopic lacrimal gland involving the deep orbit and lateral canthus have been previously reported. A 75-year-old female with a slow-growing, large pleomorphic adenoma arising from ectopic lacrimal gland tissue in the left upper eyelid is described in the present case report

Different patterns of orbital roof involvement by cholesterol granuloma

Two patients presented with cholesterol granuloma [CG], with completely different patterns of orbital roof involvement. One patient had a large intraorbital cystic CG, whereas the other had a very large intraosseous CG of the frontal bone. The presentation of CG with variable orbital roof involvement highlights the importance of being aware of the clinical characteristics and the imaging features of CG

Utility of meibography in the evaluation of meibomian glands morphology in normal and diseased eyelids

To study the utility of meibography for the morphology of meibomian glands in normal eyelids and in various eyelid diseases. A cross-sectional study. A newly designed transilluminator, fitting both the upper along with lower eyelids, and an infrared camera were used to obtain video clips of the meibomian glands for 60 asymptomatic subjects with normal eyelid margin. Parameters studied included, ocular surface, Schirmer test, and tear breakup time [TBUT]. The meibomian glands of patients with meibomian glands' abnormality secondary to infectious, inflammatory, malignant, congenital, or post-radiation therapy disease related etiologies were compared with normal patients. Still pictures were extracted from the video clips to evaluate the meibomian glands for gland dropout and gross morphological changes. In normal subjects, meibomian glands appeared to be thinner and longer in the upper eye lids than in the lower eye lids. Gland dropout occured with increased age, more in the lower eye lid and in females. Excessive gland drop out [> 75%] was seen in patients with history of trachoma, Stevens Johnson syndrome, severe blepharitis, and post-radiation for orbital tumors. Variable gland drop out was noticed in patients with floppy eyelid syndrome, and blepharitis. In patients with congenital distichiasis, partial or complete gland drop out at the part of the eyelid margins affected by distichiasis was noticed. The newly designed transilluminator permitted the examination of both upper and lower eye lid meibomian glands with minimal discomfort. Evaluating the anatomical changes involving meibomian glands with meibography may help increase our understanding of the meibomian gland-related diseases, monitor the effects of treatment, and provide helpful information for patient education

Lower eyelid swelling as a late complication of bio-alcamid filler into the malar area

To report the late complications associated with permanent filler injections into the malar area for rejuvenation. A retrospective case series of three patients who presented with lower eyelid swelling several years following injection of polyalkylimide [Bio-Alcamid] into the malar area. All patients presented with lower eyelid swelling which developed as a result of spontaneous migration of filler to the lower eyelid. Iatrogenic migration of the filler from the lower eyelid following a trial to remove resulted in an abscess formation which further complicated the removal. Lower eyelid swelling may be one of the late complications associated with the permanent fillers into the malar area. An attempt at removal of filler by aspiration or bimanual expression may result in late migration of the product and the development of eyelid swelling

Facial nerve palsy: providing eye comfort and cosmesis

Development of facial nerve palsy [FNP] may lead to dramatic change in the patients's facial function, expression, and emotions. The ophthalmologist may play an important role in the initial evaluation, and the long-term management of patients with new-onset of FNP. In patients with expected temporary facial weakness, no efforts should be wasted to ensure proper corneal protection. Patients with permanent functional deficit may require combination of surgical procedures tailored to the patient's clinical findings that may require good eye comfort and cosmesis

Orbital Fracture: significance of lateral wall

The lateral orbital wall is the strongest among other orbital walls. However, it is commonly fractured in the setting of severe facial trauma. The fracture usually occurs at the sphenozy-gomatic suture line. In general, patients with lateral wall fractures are commonly young male who may present with mid facial swelling and some degree of deformity. In some cases, lateral orbital wall fracture may be associated with visual loss or change in mental status due to associated intra-cranial injury. Imaging studies with computed tomography is important in the proper diagnosis and planning of the surgical intervention. Management of intracranial or eye injuries should be undertaken on emergent basis. Thereafter, significantly displaced lateral wall fractures need to be repaired on timely basis. Proper realignment of the plane of the lateral orbital wall at the sphenozygomatic suture along with the other complex articulations of the zygomatic bone is necessary for proper functional and aesthetic outcome
